Coming back to the original topic, can we emulate the decentralisation of ATProto Relays in the field of mass email sending? So self/community-hosted Ghost instances don't need to pay protection money to get emails delivered to subscribers who've opted in to receiving them.
I'm thinking of an automated system where Bob clicks the link in a subscription verification email, and that sends a token to the email host approving mail from the address that will send newsletters.
